Abstract
An improved calculator structure primarily for use with photographic apparatus is disclosed. A base member carries therein certain electronics including a light sensing device which receives light from an electronic flash associated with a camera and reflected from the subject to be photographed through an aperture in the base and through one of a plurality of apertures carried by a top member which is rotatable with respect to the base about a first axis. Carried by the base member are a first set of indicia indicative of the maximum distance from camera to subject available from the electronic flash being used. The first set of indicia are viewable through a window carried by the top member. A middle member is carried by the top member and is rotatable about a second axis displaced from the first axis. The middle member carries a second set of indicia indicative of various ASA film speeds and these are also viewable through the window in the top member. The middle member also carries a third set of indicia indicative of various F stop settings. These are viewable through a cutaway portion of the top member and in cooperation with an indicia bearing means mounted on the base member.
